Driving by patients with diabetes may, however, be impaired by three factors: hypoglycemia, diabetes complications, and hyperglycemia.

Hypoglycemia unawareness may pose an increased threat to driving.

With the exception of interstate commercial driving which is subject to federal regulations, rules are determined by each state

Some states impose no special requirements for people with diabetes while others ask more detailed questions about the condition

Drivers with diabetes are identified in various ways. In about half of the states, drivers are asked if they have diabetes or a condition likely to cause altered perception or loss of consciousness while driving; if the answer is yes, a medical evaluation is usually required before a license will be issued.
